I usually hate Jamie Oliver books as his recipes are dull and uninspired basic thrown together crap (I can do that on my own without a cookbook).
Am very impressed by this one. I will not cook them in 15 mins as it mostly requires flattening or dicing up the meat and frying it, whereas I prefer to take longer and stick it in the oven. Also he uses the microwave rice and I have the time to cook normal rice. He puts a yoghurt dip with practically every meal and this is a family of yoghurt haters so will skip that part.
As with all JO recipes you need to use common sense/experience to adjust some of the amounts - if it looks wrong it probably is, but nothing major. His love of excessive amounts of olive oil is almost more than his passion for yoghurt with every meal. Everything is under spiced (for my tastes anyway).
We do eat a lot of meat with spices/sauce, salad and rice and so this is a few new ideas on that. As someone says it is a lot of salad so if that's not your idea of a good meal then I would skip it.
Recipes are done in conjunction with nutritionist (though I doubt the calorie counts are accurate as usual JO inaccurate measures of 'splashes' and pinches would make it almost impossible) so are not too bad health wise especially if you skip the fried everything and take longer to bake.
Its nothing revolutionary and I would allow 20-30mins for each meal with the adaptations I make, but I was surprised how quick they were to cook and actually tasty. Family weeknight suppers, reasonably tasty, won't take too long. I like them for days I am working.
There is nothing, however in this book to convince me that JO is actually a professional chef or make me want to eat at one of his restaurants. I would not serve the food at dinner parties either.
